To all whom t may'conoen:

Be it known that I, EDWARD HENRY SED- DON, a subject oi" the King oi Great Britain, and a resident of Brooklands, in the county of Chester', England, have invented certain new and useful Improvements in Pneumatic Tires, of which the following is a speciiication.

This invention relates to pneumatic tires formotor-cars and the like; and it consists in an improved arrangement and means foriixing the tire to the fellye The arch or horseshoe shaped tires without air-tube hitherto made have' sides overlapping the sides of the felly and are clamped to it by means of side rings or cheeks bolted to the felly. .Such tires are very difficult to put on and Atake o, as the sides of such tires, made chiefly of canvas, are very st'i and the internal diameter of the sides is smallerA than the external'diameter of the telly, which Y section.

has to be passed through one of theni,and it cannot he done Withont takingihe wheel the axle, and then only with great enpenditn re of labor and time. Making the lap' of 'the sides smaller and with beads thereon fitting into grooves turned in thehsideoi the telly only partly overcomes the dieulty and Weakens the telly.

The object of this invention is to obviate .these defects. y l

On the drawing a tire :ade and fixed in accordance .with my inve'hiiin Upon the felly a, made, as usual in motorcars,-of wood and provided with a fiat hoop b shrunk thereon, another hoop, c, is xed by a few screws d. .A The hoop c is lnarrower on the inside than on the outside and preferablyY has curved sides, so that between it and the side cheekse and fe',: bolted to the sides of the felly by bolts f, provided with nuts f', dovetail-like circular recesses or grooves narrower at the top of the hoop c than at its base are formed, as shown. The tire g is formed ywith a cylindrical bottom g tting upon the top of the hoop o and provided with a dat ring or annular lip g2 at a right angie thereto, which ring is formed of soft india-rubber. Thetire itself is formedof canvas cemented and covered inside and outside with rubber and -has'on the vside to which the` bottom g' n is shown in cross-I is connected a bead or enlargement g4, iitting into the groove on that side which is the inside 'of the Wheel when mounted on the axle ci. the car. The other side of the tire is not connected to the bottom g', but formed with a bead or enlargement g5 somewhat thicker than the dovetailed groove between the ring g2 and the cheek e', which bead is coated with soft rubber on the inside.

To fix: the tirenpon the felly, the cheek e is iirst put against the inner side of the felly and the boltsf pushed in. The hoop c is first inserted into the tire, and the latter, with the hoop, is then pushed onto the felly and the hoop @fixed bythe screws/l. `The cheek e' is then put on and secured by the nuts f. The'bead g5- and iiat ring orlip g2 are thereby squeezed between the hoop c and the bead g5, and thus a tight joint is made, While the tire is secured by the beads g4 and g5 being gripped in the dovetailed grooves between the hoops c and the eheelrs e and e'. To taire ofi the tire, the

sequence the operations is reversed. .The Whole operation of taking oft the tire and putting it on again occupies onlya few minutes,` and when taken off the interior of the tire is readily accessible for repairs. This easy removal operated from the outer side of the Wheel also facilitates the nfs/e of separate treads h, .put round the outer periphery of the tire, as these can onlyb put-on without much difficulty when the tire'ss oi the wheel.-

The tire is inflated in the usual Way through a valve n of any suitable construction.

l claim as my inventionl. In an article of manu'iiae't'ure a tire slit longitudinally at cine side'of'its inner peripheryj and having beads fat, its bottom edge adapted to t into d'ovetailgroves formed by a hoop surrounding the fellyfa'nd fixed thereto and cheeks 'attached tothe sides of the fell-y, one of said edges being .formed with a` cylindrical bottom extending across said hoop.

and having a lip et soft rubber 'at a right angle thereto adapted to be compressed by the other edge ci the tire against the side of said hoo i Ap'lhe combination with a. wheel-felly and side' cheeks forming a channel attached thereto, of a hoop surrounding said felly and fixed thereto, said hoop being wider at its cuter 'than at its inner periphery, a tire of arched ICO -shape having one side formed with 'a bed- Withlsaid bottom adapted to lie against the of the outer side 'of said tire adapted to t cheek and. to compress saidlip when the outer lo cheek is-bolted to the wheel.
